The ancient capital of Sakya kingdom (Kapilavastu) is located about 27 km west of Lumbini. Tilaurakot houses the vestiges of ancient Sakya palace where Siddhartha lived his early 29 years as a prince. The ramparts of a moat and a fortification wall with its western and eastern gates surround the remains of the citadel including ancient structural remains in the central part of the mound.
The eastern gate of the palace reminds us about Siddhartha’s renunciation for the search of supreme knowledge. He renounced the palace at the age 29 quietly at mid night from this Mahaviniskramana dwara. The eastern gate is known as Mahabhiniskramana Dwara, through which Siddhartha took the great renunciation at the age of 29. It is also known as Mangala Dwara (auspicious gate) in the Buddhist literatures.
